So the problem was there in my /usr/src dir I had a shortcut named linux, linked to 2.6.10 folder
bad setting in my distribution.
Althought, I removed this file and then installed your original package 8756. No problems appeared. Now I'm happy running my X server and using my nVidia card in its full potencial, and I'm planning to start playing games.
Keep the good work in supporting linux drivers and support, because linux is the future for the home-users.
